26th International Microlensing Conference

Celebrating the 30th anniversary of the first microlensing results

Dates: January 31–February 2, 2024

Location: Lawrence Livermore National Laboratory, Livermore, California, USA


The science topics of the conference are anything related to microlensing, including (but not limited to):

  • Astrometric microlensing
  • Interferometric microlensing
  • Detection of free-floating planets, exoplanets, brown dwarfs, stars and binaries, and compact objects
  • Cold planet demographics (observational constraints and theory)
  • Stellar populations and their properties in the Milky Way (and other galaxies)
  • Search for electromagnetic signatures of gravitational-wave sources through microlensing
  • Synergies between ground-based facilities and/or space missions (Gaia, Roman, Euclid, Rubin, ELTs, etc.)
  • Data mining, numerical tools, and techniques

In addition to typical conference activities, the conference will also pay tribute to the original MACHO, OGLE, and EROS surveys.


We invite people to preregister their interest in attending the conference (either in person or remotely) and request visa invitation letters by completing our preregistration form by September 30, 2023.
